Application
Interfaces
2G/3G/4G antenna, diversity antenna, GNSS antenna
50Ω impedance
Two UART interfaces: one is an ordinary serial port, and one is used for
Bluetooth by default
One I2C interface, supporting only host mode
One SPI interface, supporting only host mode and max. 50 Mbp
One USIM interface, 1.8V/2.85V
One USB2.0 interface, OTG function requires external 5V DC-DC
2
Sleep mode is the low power consumption state the module enters. In this mode, peripheral interfaces of the module
are disabled but the RF function works. If a call or SMS message incomes, the module exits from sleep mode. After the
call or voice is end, the module enters sleep mode again.
3
Idle mode indicates the status of no service when the module is running.
4
Current in operating mode indicates the current during data communication. For currents of other network modes
and bands, see N75-NA Current Test Report.
